As far as I know it was Netscape that invented SSL. They picked a scheme
that was provably secure (from math point of view), which was good.

And comparing SSH and SSL is not totally fair - usage differs. It is
much more of an incentive for a criminal to intercept first SSH
connection to a bank (supposing SSL was not invented) than to random
hosts out there. And there are much more connections to a bank than
there are SSH login attempts to a host.

One of the reasons why there is (seemingly) no threat because SSL is so
pervasive, and it takes a lot of effort to break SSL.

I wouldn't say so. People do think about security to some extent, but
many are checking the wrong things, or they ignore the warnings they
get. Ignoring warnings can be due to various reasons, only one of which
is people consciously ignoring security. Others include badly configured
websites that require users to ignore the warnings, or users really
wanting to use the service even though it may be against their best
interest, and not understanding the implications of the warnings.

Are you inventing history here? I don't remember what the early
browser's looked like, but was there really more security in the early days?
